WARM-AIR GENERATOR.

Application filed August 17, 1925. Serial No. 50,889'.-

ion relates to improvements in warm air generators, as applied to and incorporated in heating apparatus designed -for heating;` ot houses and other @ne ot the insure that the units expended heatingl medir buildings. objects ci the invention is to maxinmn'i amount ot' heat in inducing heat into the Lili Another object otthe invention iste insure that the as high a te beingdischarged inte the area to be heated shall attain possible beiforc be heated.

air to inperature as Another object oi the invention is to provide means for heating pure atmospheric air,

without placingv minglingl it with the it in contact, or coni'- g'ases and other products ot combustion applied in the air heating` operation.

The invention has other features which will be more Vfully described in connection with the accompanying' drawings, and which will be pointed out claims.

Near the top ot 'the casing; and spaced away from said top,

is the iiue opening1 7 which leads by suitable means to the chimney (not shown), for carrying oil' the products oi combustion.

The air inlet led to a common heat ,ogen 8, positioned centrally within LeadingV from the heat gensuch as air, will be utilized eratinp,` retort which eaten ds 8, is the hot air conduit 9, from tli retort 8 to the top wall of the casing' where it discharges the hot air into th e area to be heated.

IVhile I have shown one form of my invention, I do not limit myself to the specific forno shown, as modifications be made Without departing from the Ispirit oit my invention.

I/Vhat I claim as new, and desire to secure by Letters Patent is:

I. In a Warm air generator, the combina- Y tion of an outer casing having ay perforated bottom, a plurality of vertically disposed air lues positioned in parallel rows mounted in apertures in said bottom, a gas burner positioned intermediate of said air flue rows, a. horizontally disposed air chamber1 mounted on the upper ends ot said air Hues provided with a common conin'iunication therewith, a rectangular formed discharge lair port located in the upper Wall ot' said air .chamber and having a longitudinal dnnen sion comprising several multiples of itsl dimensional Width, an air discharge conduit mounted on said discharge port and formed with a Warm air discharge opening in the Vupper end thereof and having substantially thereof may the same cross sectional form as the discharge port throughout its length.

2. In-a Warm air generator, the eo1nbination of an outer casing having an apertured bottom Wall, a plurality of air lues positioned in parallel lines extending upwardly from the apertured bottom Wall, a longitudinally disposed airr chamber having communication with said air tlues, a gas burner interposed between the parallel lines of air fines and adapted to project the kproducts of combustion against the vair fines and air chamber in common, a rectangularly formed discharge port located in the upper wall of said air chamber Whose longitudinal dimension comprises Aseveral multiples of its dimensional Width, an air discharge conduit mounted on said discharge port having substantially the same cross sectional form as thediseharge port throughout its length and having a discharge orifice positioned out of vertical alinement with said discharge port, for the purposes described.

In testimony whereoil I have aiixed my signature.
